Thermal expansion during welding occurs primarily due to uneven heating and cooling. Weld shrinkage, which leads to Distortion, significantly impacts welding quality for experienced and novice welders. Proper deformation can be minimized by carefully designing joints, controlling the welding process, and effectively employing post-welding treatments to minimize Distortion. Here\u2019s a detailed overview of strategies to […]<\/p>","protected":false},"author":1,"featured_media":14882,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[],"class_list":["post-14885","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cnc-basic"],"_links":{"self":[{"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/posts\/14885","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/comments?post=14885"}],"version-history":[{"count":1,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/posts\/14885\/revisions"}],"predecessor-version":[{"id":14886,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/posts\/14885\/revisions\/14886"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/media\/14882"}],"wp:attachment":[{"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/media?parent=14885"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/categories?post=14885"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stcncmachining.com\/cs_cz\/wp-json\/wp\/v2\/tags?post=14885"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
